To aZZ whom it may concern: y

Be -i't known that we, HERMAN FJOHMN and -JoirN HIGHAM, ycitizens vof the United States, residing at Los Angeles, in the 'county of Los Angeles and State of California,'liave invented new and uset'ul lmproveinentsnin Camp-Stoves, of which the ollowing is a specilication.

This invention relates to camp stoves Aand especially pertains to camp stove-structures which may be collapsed and'made convenient 'to transport.

1t is the primary object :of this invention to provide a stovey construction rot sheet metal which may be quickly unfol'dedi'rom itsrfcollapsed t'orm, locked in open position and which will bestro-ng and rigid-in such opened position. Y

f 1t is a still urtlierobj'ect to provide a stove pipe which is vcollapsible and when folded can be disposed within the folded stove, thus forming a small package adapted for `easy transportation. Y Y

The embodiment of our invention -fdisclosed herein comprises a Ystove which has a body of lbox-like orm with an open front end and an open bottom, the side wallsbeing hinged to the top wall so that they'V will i'old underneath and the back wall being hin-ged so that it will be folded above. AY collapsible lstove pipe which is triangular in section is provided, thus forming astructure which may be easily collapsed. y

ln the accompanying drawing:

Fig. 2i's 'an enlarged plan View." p

Fig. 3 is a vertical section through the stove.

Fig 4 is a fragmentary section taken on the line 4 4 ot' Fig. 3.

Fig. 5 is a fragmentary section taken on the line 5*?) of Fig. 4.

Fig. 6 is an enlarged horizontal section taken on the line 6 6 of Fig. 1.

Fig. 7 is a plan view of the stove pipe.

Fig. S is a view of the stove pipe collapsed.

More specifically, 9 indicates the top wall of the stove and is preferably of sheet iron, rectangular in form, and having end portions 10, 11 and 12 bent downwardly at right angles to form flanges, whereby a tight Joint is provided, thereby preventing smoke from passing outward except by the stove pipe, or

air-enteringthe "combusti-bn --ehamb'er except at the front opening. Side :walls 13 and'1'4 of rectangular 'form 'andpreferably ofsli'eet iron, v'are pivotafll-y 'secure-d adjacent the side edges 'of top *wa-i119 Ylay fof hinges.

The side walls 13 'and Y14. have their "upper edge lportions bent over 'to lorrn l`a Y'closed channel within-which yh'i'ng'e pin 17 "is disposed. The `walls have porti-ons I'cu'tjout to accommodate the leaves 16. Y y l The lower edge zoflea'clrof the end walls 'is bent inwardfto formlanges 20 'a1`idj21 which serve as snpporting'feet when the lstove is placed upon the ground. Side vwalls 13 and 14 are preferably provided Iwith Vslots 22 and 23 vdisposed at rthe rear rvportion of the wall and with their longest Vdnmens-onverri-cai.

ivotally 's'ecuredto the rear A'edge of top wall 9 is lend wlall 24, preferably *of #sheet iro-n, and pivoted rto the top 'wall by means of hinge leaves 25 and 26. The side ledgesof end wall 24 are provided fw'i-'th tongues 27 'and 2:8y adapted to be passed 'through the -slots 22 Vand 23. vPivotally securedpto end walls 131and 14 adiacentisl'ots22 and y23are latch hooks 29an'd-.30 adapted to `engage lthe 427 .Mld Q38. k

A triangular aperture Vr3'1 is formed in the upper wall *9 and is adapted 'to receir'fe the stove -p'ip'e '32 which is in the forni "of 'a triangular prism having one waflllr3^3 fofr'med with end flanges 34 `and 35 which are vturned inward at angles of approximately AGO 'degrees. LHinfge leaves "are ksecured 'preferablyby rivets to wail -33 and -are adapted {t receive pins 37, which also pass through r"channels 'forme-city bending wail B8. Wall Vl38has one edge bent inward to form a channel for the reception of the hinge pin 37 and slots cut in its edges to accommodate hinge leaves 36. The free end of wall 38 is bent inward at an angle of approximately 60 degrees to form a flange 39. Wall 40 is pivoted to wall 33 by hinge leaves 36, a hinge pin 37, and bent portions which form channels.

In its open form walls 13 and 14 are bent outward until they are stopped by abutting flanges 10 and 12 of top wall 9. End wall 24 is swung downward at right angles to top wall 9, the walls 13 and 14 are sprung outward so that tongues 27 and 28 may be passed through slots 22 and 23. LatchY hooks 29 and 30 are then disposed to engage the tongues 22 and 23 and thus securely hold them in position, the ends'lll of, the latch hooksV passing through vapertures in theA Y swung inward and the collapsed pipe takes the forin shown in Fig. 8. Latchliooks 29 and 30 are released froin tongues. 27 and 28. The side walls 13 and 11 are'bent outward to disengage the tongues troni the slots 2Q andl 23 and wall 2l is' swung upward against the top of the stove. Walls 13 and 14 are then folded inward `to positions shown in dotted lines in Fig. 3. The stove and pipe are now in condition to be packed away in a very small space.v

' Special attention is called to the downturned flanges at the sides of the top wall, the side walls hinged to the top wall so as to swing outwardly against the flanges, and the i end wallhinged to the top wall so as t0 `(Jopies of this patent maybe obtained for swing between` the ends of the side walls and brace the side walls. This construction produces a very substantial stove when set-up, is easily collapsed, and folds into a very small package'. n

What we claim is:

l. A Acollapsible stove, comprising a top wall provided with a stove pipe hole and uninterrupted flanges at its side edges, hinges secured to said top wall adjacent said iianges, side walls secured to said hinges and so disposed that when said stove is open said side walls are iny Contact with said lianges, an end wall pivoted to said top wall with its edges arranged to be disposed between and in contaetwitli said side walls when the stove is open, said end wall provided with tongues arranged to extend through openings in said side walls when the stove is placed n cent said flanges, side walls secured to said hinges and so disposed that when said stove is open said side walls are in contact with said lianges, an end wall pivoted-to said top Vwall with its edges arranged to be disposed between and in contact with said side walls when the stove is open, said end wall providedwith tongues arranged to extend through openings in said side walls when the stove is open, catches for engaging said tongues and locking the stove in open lform, a collapsible stove pipe adapted to be disposed in said stove hole comprising a Vwall having flanges at its sides, hinges adjacent said flanges and two walls secured to said hinges so that when open the last mentioned walls are in contact with said flanges, one of said last mentionedwallshaving a flange at its free edge arranged to over-lap the othervof said last mentioned walls when in open form.

3. A collapsible stove comprising a top wall provided with down-turned flanges at its side edges, side walls hinged to the top wall so as to swing downwardly to vertical f i positions and engage the flanges, an end wall hinged to the top wall so as to swing between the ends of the side walls and hold the side walls expanded against the flanges, there being slots in the ends of the side walls and tongues extending from the ends ofthe end wall to snap through said slots, and hooks connected to the outer faces of the side walls to engage; said tongues.

In witness that we claim the foregoing we have hereunto subscribed our names this 31st day of March, 1915.
